How the General Pump 96735000 Washer Works in Your System

Understanding where the 96735000 washer sits and what it does helps you appreciate why correct installation matters. Here's a simplified overview of the process:

1. Water intake and initial pressurization – Water enters the pump through the inlet, passes through filters and fittings, and fills the pump head cavities. The washer sits at the head end of each cylinder, positioned between the head ring, anti-extrusion ring, and plunger, where it provides a rigid sealing surface that keeps these components properly aligned and compressed.

2. High-pressure generation – As the engine or motor turns the drive shaft, the triplex plunger pump's three ceramic plungers cycle in and out, pressurizing water against the valve and seal stack. The 96735000 washer ensures the seal stack remains correctly seated during each pressure cycle, preventing internal bypass and maintaining full PSI output.

3. Controlled output to spray device – Pressurized water exits through the outlet to the hose and gun, where the unloader or regulator controls working pressure. If the washer is worn or missing, pressure can bleed past the head assembly, reducing output at the gun and stressing adjacent components.

Proper water supply and correct nozzle size are critical for correct operation - even a perfect washer can't compensate for a starved inlet or oversized orifice.

Installation and Setup Overview

This is a high-level overview of the washer replacement process. Always read and follow the official installation instructions and parts breakdown for your specific EZ Series 44 model before beginning work.

• Verify compatibility – Match your current pump's model tag, suffix (E, G, or S), and plunger bore size to the 96735000 washer specifications. Cross-reference the exploded parts views to confirm item 30 corresponds to this part number in your pump's documentation.

• Prepare the machine – Shut off the engine or motor, disconnect the spark plug or power source, relieve all system pressure by squeezing the trigger gun, and drain remaining water from the pump head.

• Remove the head assembly – Remove cap screws and carefully lift the head or valve plate away from the pump body. Note the arrangement of washers, head rings, anti-extrusion rings, and O-rings as you disassemble.

• Inspect and clean all components – Clean mating surfaces, inspect the plunger bores, and examine adjacent seals. If head rings or O-rings show wear, plan to replace them at the same time.

• Install new 96735000 washers – Set one new washer in each of the three cylinder positions, ensuring correct orientation and seating against the adjacent head ring and anti-extrusion ring.

• Reassemble and torque – Reinstall the head plate and tighten cap screws evenly to the recommended torque (approximately 29.4 ft-lbs / 40 N·m for EZ44 pumps). Avoid over-tightening, which can crack the brass manifold or distort sealing surfaces.

• Prime and test – Turn on the water supply, purge air from the system by running water through without starting the engine, then start the engine and slowly bring the pump to working pressure while checking for leaks around the head.

Safety reminder: Never run the pump without an adequate water supply. Operating dry - even briefly - can destroy seals, plungers, and the washer you just installed.

Care, Maintenance, and Longevity Tips

Simple routine care can significantly extend the service life of your 96735000 washers and the entire pump assembly.

• Check pump oil level regularly – Inspect the oil bath sight glass or dipstick before long work sessions and add recommended pump oil when needed. The oil bath lubricates the crankcase and protects internal components from premature wear.

• Change pump oil on schedule – Perform an early break-in oil change after the first 50 hours, then change at regular intervals based on your hours of use and operating conditions.

• Keep inlet water clean and adequately supplied – Use a proper inline filter or strainer and avoid running the pump on a restricted or low-flow water source. Starved inlets cause cavitation that accelerates wear on washers, seals, and plungers.

• Inspect hoses and fittings – Regularly check for leaks, damaged O-rings, and worn couplers that can stress the pump or introduce air into the system.

• Use correct nozzles – Match nozzle orifice size to the pump's intended pressure and flow. An oversized nozzle drops PSI; an undersized one overloads the pump and unloader.

• Protect from freezing – Drain or winterize the pump with suitable pump saver fluid before storage in cold climates. Frozen water inside the head can crack the manifold and destroy washers and seals.

• Watch for early warning signs – Noise, pulsation, pressure loss, or milky oil may indicate valve, seal, or water-in-oil issues that should be addressed promptly before they cascade into more expensive repairs.

• Plan periodic seal and valve service – For heavy users, internal rebuild kits can restore like-new performance. When you're already inside the pump head, always replace the 96735000 washers at the same time.

Troubleshooting Common Issues with the 96735000 Washer

If your pump isn't performing correctly after a rebuild or during regular use, these common symptoms can help you narrow down the cause:

• Low or fluctuating pressure – Possible causes include air in the system, a clogged inlet filter, worn nozzles, or internal valve and seal wear. Start by checking the water supply, filters, and nozzle size. If those are fine, inspect the 96735000 washers and adjacent head rings for signs of wear, deformation, or incorrect seating.

• Pump runs but no pressure at the gun – This may indicate the unloader is bypassing, the nozzle is blocked, or the pump has an air lock. Verify unloader set points and ensure the system was properly primed before use.

• Visible water leaks at the pump body – Worn washers, damaged O-rings, or cracked fittings are the usual culprits. Shut down immediately, relieve pressure, and replace affected components. A bent or incorrectly sized washer can create a leak path even when other seals are new.

• Milky or foamy pump oil – This is typically water contamination entering the crankcase through worn plunger seals. Stop use immediately, change the oil, and inspect all seals - including the 96735000 washers, which may have allowed misalignment leading to seal failure.

• Loud knocking or grinding – Potential mechanical wear, lack of lubrication, or a foreign object in the valve area. Shut down immediately and seek professional inspection before running the pump again.

• Overheating during bypass – Extended trigger-off operation without cooling flow can overheat the pump and damage internal components. Limit bypass time and consider installing a thermal relief valve where appropriate.
